Chapter 1 Introducing the Option BrightStor® ARCserve® Backup is a comprehensive, distributed storage solution for applications, databases, distributed servers, and file systems. It provides backup and restore capabilities for databases, business-critical applications, and network clients. Benefits of Using the Option Disaster recovery is a backup and recovery process used to protect computing environments against the loss of data caused by a catastrophic event or natural disaster.
Understanding How the Option Works Understanding How the Option Works The option is based on the concept of collecting and saving machine-specific information before a disaster strikes. Whenever a full backup job is submitted, the option automatically generates and saves emergency data information for the node, locally on the backup server, on backup media, and, if configured, on a remote computer. In the event of a disaster, the option can recover its protected computers to their last full backup state.

Appendix A Disaster Recovery in a SAN Configuration BrightStor ARCserve Backup Disaster Recovery Option supports Storage Area Network (SAN) configurations. You can recover primary servers and distributed servers in the SAN settings in Windows 2000 and Windows 2003 environments. Backing Up the SAN There are no special configurations or settings required to recover primary and distributed servers.
Appendix B Recovering a Cluster Disaster recovery in a Windows-based cluster environment is a complex task. Although BrightStor ARCserve Backup makes it easier to recover your mission-critical cluster environment, it still requires some planning and effort. It is important that you understand the concepts described in this guide, and test the scenarios suitable for your specific environment.
Requirements Hardware Requirements ■ ■ ■ The hardware for a cluster service node must meet the hardware requirements for Windows 2000 Advanced Server or Windows 2003 Server. Cluster hardware must be on the Cluster Service Hardware Compatibility List (HCL). Two HCL-approved computers comprised of the following: – A boot disk with Windows 2000 Advanced Server or Windows 2003 Server installed. The boot disk cannot be located on the shared storage bus.
Special Considerations Special Considerations ■ ■ ■ Partial shared disk configuration, in which some disks are owned by one node and some disks are owned by another node, is not recommended. To avoid complications when matching disks, shared disks should be the last disks and have the highest number when viewed from Administrative Tools, Computer Management, Disk Management. Run the dumpcfg.exe utility (available on Windows 2000 or Windows 2003 Resource Kit) to save the cluster quorum disk signature.
Terminology Terminology The following table defines common cluster terms. Term Definition Primary node Refers to the node that owns all shared disk resources during backup. Secondary node Refers to the nodes that do not own any shared disk resources during backup. Quorum Disk A shared disk used to store cluster configuration database checkpoints and log files that help manage the cluster. This disk is critical to restore the cluster service.
Checklist for Disaster Recovery on a Cluster Checklist for Disaster Recovery on a Cluster You must have the following information to recover failed clusters. Use this list as a checklist to ensure that you have collected all of the necessary information: ■ Cluster name ■ Cluster IP address and subnet mask ■ Cluster node names ■ Cluster node IP addresses ■ The assignment of all drive letters including all private and shared hard disks. ■ All disk signatures.
Recovering from a Cluster Failure The following scenarios outline the steps you can take to recover from various types of cluster failure. Note: If no tape device is attached to any of the cluster nodes, you can remotely recover a cluster service using the option. To do so, follow the instructions on performing a remote disaster recovery. Scenario 1: No Shared Disk Failure The following cases are the most common failures in the Windows cluster environment.
Recovering from a Cluster Failure Recovering the Primary Node in the Cluster To recover failed secondary disks and ensure the cluster is working properly, perform the following steps: 1. Disconnect shared disks from primary node. Note: On most cluster machines, for example, Compaq Proliant CL1850, there is no need to shut down the shared disks. This allows the cluster to function during disaster recovery.
Recovering from a Cluster Failure Method 1 1. Open the Windows Service Control Manager and set the cluster service startup type to Manual. 2. Reboot the system and format the inaccessible shared disks using the BIOS level SCSI adapter utilities or RAID adapter utilities. The management console of the disk array has utilities to format disk slices if you are using a high- end Fiber Channel disk array. 3. Restart the server to access the shared disk. 1.
Recovering from a Cluster Failure 3. Follow the restoration procedure to recover the data to a non-quorum shared disk. Select the full volume restore to recover all lost volumes in the shared disks. 4. Connect the shared disks to a secondary node. 5. Start the secondary node. Your cluster should now be back online. Recovering a Cluster Quorum Disk with No Node Failures in the Cluster You can use two methods to recover cluster quorum disks.
Recovering from a Cluster Failure The System State Restore Options dialog opens. 7. Restore the lost shared disk by performing a whole volume restore in BrightStor ARCserve Backup. 8. Start the cluster services on the primary node. 9. Connect the shared disks to the secondary node. 10. Start the secondary node. If cluster nodes are Active Directory Servers: 1. Stop cluster services on the secondary node. 2. Shut down the secondary node. 3.
Recovering from a Cluster Failure 6. Recreate and format the old partition layout according to your disaster recovery on a cluster checklist. Reassign old drive letters and volume labels according to your checklist. 7. Restore all shared disk partitions by performing a whole volume restore using BrightStor ARCserve Backup. 8. Run the caclurst.exe utility to load the cluster database from the following: %windir%\clusbkup caclurst.exe is available from the BrightStor ARCserve Backup home page.
Recovering from a Cluster Failure Recovering All Shared Disks with No Nodes Failures in the Cluster You can use one of two ways to recover your cluster quorum disks. Use the first method to recover your quorum disk using the integrated cluster support included in the option. Method 1 If cluster nodes are not Active Directory servers: 1. Stop cluster services on the secondary node. 2. Shut down the secondary node. 3. If the cluster quorum disk is physically damaged, perform the following steps: a.
Recovering from a Cluster Failure If cluster nodes are Active Directory Servers, then: 1. Stop cluster services on the secondary node. 2. Shut down the secondary node. 3. If the cluster quorum disk is physically damaged, perform the following steps: a. Shut down the primary node. b. Replace damaged shared disks with new disks. c. Restart the primary node. d. Have your checklist handy. 4. At this point the cluster service does not start. You may not be able to access the shared disk. 5.
Recovering from a Cluster Failure 4. Restart the primary node. Have your disaster recovery on a cluster check list handy. At this point the cluster service startup fails. 5. To start the cluster service on primary node, enter: %windir%\cluster\clussvc -debug -noquorumlogging The cluster shared disk is now accessable. 6. Write back the quorum disk signature by running dumpcfg.exe –s [disk signature]. 7. Restore the lost shared disk using BrightStor ARCserve Backup.
Recovering from a Cluster Failure Recovering an Entire Cluster To recover an entire cluster, perform the following steps: 1. To recover all secondary nodes, perform the following procedure: a. Stop the cluster services on all nodes. b. Disconnect shared disks from the secondary node. c. Shut down all nodes. d. Follow the disaster recovery procedure to recover the secondary node. e. If there is more than one secondary node, repeat the above steps to recover all secondary nodes. f.
Recovering from a Cluster Failure To recover a cluster with a partial shared disk configuration, perform the following steps: 1. Recover one node with some shared disk resources by performing the following steps: a. Stop cluster services on all nodes. b. Disconnect shared disks not owned by this node during backup. Note: Refer to your Disaster Recovery on a Cluster checklist and dumpcfg.txt to identify which shared disks are not owned by this node c.
Appendix C Frequently Asked Questions This appendix provides answers to some commonly asked questions that you may have when using the BrightStor ARCserve Backup Disaster Recovery Option. To help you quickly find the answers to your questions, the information in this appendix is divided into the following categories: ■ General usability ■ Hardware ■ Operating systems ■ Utilities Each category is further divided into questions for specific operating systems.
General Usability Question: What system configurations should I avoid for disaster recovery? Answer: For all Windows NT platforms, you should avoid the following configurations. ■ ■ ■ ■ ■ The option cannot recover your system if the boot volume is larger than 4 GB. The option cannot always recover stripes, spanned, and mirrored volumes. For system volumes of these types, you should first, recover the system; and then recreate the striped, spanned, and mirrored volumes using windisk.exe.
General Usability Question: Should I add extra drivers during the disaster recovery procedure? Why doesn’t the disaster recovery process detect my SCSI, Fiber, and RAID adapters? Answer: Mid to high-range servers typically require drivers for RAID and SCSI adapters. The option uses these drivers to access the disks and storage devices in the system. Without these drivers, the option may not function properly.
General Usability Question: Can I use the option to back up remote machines over the Network? Answer: BrightStor ARCserve Backup Disaster Recovery Option is only supported over the network when the BrightStor ARCserve Backup Client Agent for Windows is installed on the Windows machine. Question: Can I use disaster recovery as a “ghost” application to duplicate my system configuration? Answer: No. The option is a system restoration application, not a system configuration replication program.
General Usability Question: How can I update the machine-specific disk if my BrightStor ARCserve Backup server fails? Answer: You can update a machine-specific disk if you configure an alternate location for backups during or shortly after installing the option. To update a machine-specific disk on a backup server, access the alternate location and copy the contents of the folder representing the server that you want to recover and copy its contents to a blank disk.
General Usability Question: Can the option restore the EISA (Utility) partition on my server? Answer: No. The option does not back up EISA partitions, and cannot recover these partitions using the disaster recovery process. You must recreate these partitions manually. Use the CD or disks provided by the hardware vendor to recreate these partitions. Do not use the Disaster Recovery Wizard to create or delete partitions.
General Usability Question: Can I change partition information during disaster recovery? Answer: No. If disk configuration is changed manually during the disaster recovery, you may not be able to restore the system. Question: I do not want to restore the last full backup sessions for a local disaster recovery in Windows 2000. What can I do? Answer: Use the DRScanSession utility to modify the machine-specific disk and perform a disaster recovery.
Hardware Question: My original system has a Windows 2003 Server Edition operating system. Can I perform disaster recovery using the Windows 2003 Enterprise Server Edition CD? Answer: No. You should not use a different version of the operating system’s CD to perform the disaster recovery process. Question: To back up my server, I am using a GFS rotation scheme consisting of a full backup on Monday and incremental backup for the rest of the week.
Hardware Question: During a restore, I received a message saying different dll files cannot be found. What is the problem? Answer: This is not an error, and can be ignored. Although this message can alarm you, the disaster recovery is operating properly, despite this message. This occurs if the systems hard disks are not clean while performing the disaster recovery process. When the disaster recovery process restores the original registry hives, the services in that hive start.
Hardware Windows 2000, Windows XP, and Windows 2003 Platforms The following section applies to questions and answers for Windows 2000, Windows XP, and Windows 2003 platforms. Question: I have two or more fibre channel adapters on the server connecting to the same SAN network for fault tolerance purposes. When I try to recover the server using the disaster recovery process, the disaster recovery fails with tape engine errors.
Problems Relating to Operating Systems Problems Relating to Operating Systems Windows NT, Windows 2000, Windows XP, and Windows 2003 The following information applies to Windows NT, Windows 2000, Windows XP, and Windows 2003 platforms. Question: When performing a remote recovery on Windows NT 4.0, the recovery fails to connect to my backup server, which is a Windows 2003 Active Directory Server.
Problems Relating to Operating Systems Question: I want to create a disaster recovery boot tape/disk set for a specific machine, but it is not listed as a choice in the Disaster Recovery Wizard. Answer: For a machine to be accessible for a disaster recovery boot kit, a full backup must be performed on that machine. If a machine is selected for a full backup, the selection box for the machine is solid green. If this machine is remote, the backup must be performed using the client agent for Windows.
Problems Relating to Operating Systems Question: My remote disaster recovery fails with the message “failed to connect to the server.” How can I find out why this happens? Answer: To determine why the message “failed to connect to the server” was generated, perform the following steps: 1. Open a command prompt window. 2. Ping 127.0.0.1 and localhost. If this fails, the protocol stack was not installed. 3. Ping any machine in your sub-network. If this fails: a.
Problems Relating to Operating Systems d. Verify that you can connect to the BrightStor ARCserve Backup server from a different system by running the “net use” command. e. Verify that you do not have any anti-virus, firewall, or server protection software running on the backup server, thus preventing remote access to the server. f. If you are running Windows XP or Windows 2003 on the backup server, you must reduce the security level to allow other systems to connect to the backup server.
Problems Relating to Operating Systems Question: How can I verify that the storage device attached to the system is functioning properly during a local disaster recovery? Answer: It usually takes some time for a changer to initialize. Do not stop the disaster recovery process during this time. See the following instructions. If you are using a changer, use the chgtest utility from the disaster recovery command prompt. This utility is not copied during the disaster recovery process.
Problems Relating to Operating Systems Question: When the disaster recovery process is in the blue screen text setup mode, it is asking for some missing files and I have to press Esc in order to proceed with the disaster recovery process. Why? Answer: This could happen if the CD media is corrupted or the Microsoft Windows CD being used to create the bootable media is a Microsoft Developer Network (MSDN), pre-release version CD. Recreate the bootable media using the Microsoft Windows CD.
Utilities Question: After creating the bootable CD image for a Windows 2000 disaster recovery, the machine to be recovered could not boot from the bootable CD. Why? Answer: The following is a list of common causes for the problem. ■ The CD drive is not bootable. ■ The CD media itself is corrupted. ■ The system boots from the hard drive or diskette drive first. ■ The disaster recovery bootable CD image file, cdboot.iso, was copied improperly onto the CD media.
Utilities The following are useful functions of the tapetest utility: ■ You can display a list of devices on the screen. To determine the devices to use with other tapetest options, or to identify the devices BrightStor ARCserve Backup detects are attached to the machine, enter the following at the prompt: tapetest –y ■ To test that BrightStor ARCserve Backup can successfully communicate with a device, enter the following: tapetest -d# -ping where d# is the device number.
